Artificial photosynthesis is a viable approach for transforming carbon dioxide (CO2) into value-added chemicals driven by renewable solar energy. Studies on photocatalytic CO2 reduction (CO2R) have thus been expedited in recent years. Cadmium sulfide quantum dots (CdS QDs) regarded as one of the most promising photocatalysts, offering myriad advantages CO2R, such narrow band gap, confinement effect, and tunable redox potential. However, CdS QDs usually suffer from photo, thermal, oxidative...
Photocatalytic reduction of carbon dioxide (CO2), so-called artificial photosynthesis, has been regarded as the future technology with high potential to sustainably address global warming. However, efficiency and stability catalysts used in this frontier are substantially lower than requirement for practical application, especially gas-phase reactions.

Abstract Although single‐atom catalysts (SACs) show significantly higher catalytic performance compared to conventional and nanoparticle‐based (NPs) at the same amount of metal loading, their overall may still be unable compete with NPs in many applications due limited active sites. Generally, trace amounts (less than 1 wt%) can successfully loaded onto supports an atomically‐dispersed feature, loading usually results aggregation atoms. Hence, it is very important further increase density...
